Mississauga Office is slowww as well. A lot of 2019 applicants still waiting for Oath even though their file has "Decision Made" in July/August of 2021.
So you are not alone and you are lucky if your file moves faster than 2019 applicants. I just applied for GCMS notes in Oct. and received them today. It says file is kept in "Ceremony Ready Shelf" since July end... But no oath while some 2020 applicants in Mississauga office already got oath. Unfair practices.
